IPsec VPN Over Drop-In Mode with Shared IP Configuration on Peplink Balance

Product Discussion Peplink Balance

Hi Peplink Community,

I have a Peplink Balance configured in Drop-In Mode in front of a Sophos firewall. Both devices are sharing the same public IP address (x.x.x.x/30) using the Shared IP option.

My question is:
Is it possible to use this public IP, shared between the Peplink and Sophos, to establish IPsec VPN connections with remote sites? Alternatively, could I use SpeedFusion tunnels for this scenario? If so, are there any specific configurations required to ensure the IPsec or SpeedFusion traffic is properly routed without interference?

Thank you for your assistance!
